The speed of the spreading and its tremendous impacts to economic is unprecedented in half a century. Through researching its impacts to finance, the authors can clearly find that to a large extent most enterprises went bankrupt and closed down because of the weak financial governance system and lack of effective control to internal financial operation Based on this background, the authors analyzed the problems of the traditional financial governance, and tried to find solutions. Applying the concept of COSO （The Committee of Sponsoring Organizations of The National Commission of Fraudulent Financial Reporting） framework into the financial governance system, the authors can reconstruct the embedded financial governance system based on COSO framework, and better control the company＇s financial activities. In this way, the enterprise can effectively improve its management level and operational efficiency, and promote its sound and sustainable development.展开更多

A common fixed point theorem for sequence of continuous mappings in Menger spaces is proved. These mappings are assumed to satisfy some generalizations of the contraction condition. The proving technique herein seems to be new even for mappings in Menger spaces.展开更多

Two kinds of flat plate spreader of pulsating heat pipe are designed, fabricated and experimented. For the embedded circular capillary type, the transferred heat flux could reach 32 W/cm2, the smallest thermal resistance for acetone, methanol and FC-72 were respectively 0.50, 0.57 and 0.40℃/W. While for the square capillary type, the transferred heat flux could reach 26 W/cm2, the equivalent thermal conductivity could reach 3211 W/（m. ℃）. There are ranges of optimal transferred power and filling ratio for different working liquid. If the transferred power is constant, changing the heating area and the place has little effects on the performance.展开更多
